SETH W. LOWELL, OF HUME, NEW YORK, ASSIGNOR OF TWO-THIRDS TO FRANK S. BELOHER AND JOHN B. BELOHER, OF CHARLOTTE, MIGH.

STEAM VEGETABLE AND FRUIT EVAPORATOR.

SPECIFICATION forming part of Letters Patent No. 258,536, dated May 23, 1882.

Application filed November 23, 1881.

To all whom it may concern:

Be it known that I, SETH W. LOWELL, a citizen of the United States, residing at Hume, in the county of Allegany and State of New York, have invented certain new and useful Improvements in Steam Vegetable and Fruit Evaporators, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to steam fruit-evaporators and it consists in the construction and arrangement of its several parts, as will be hereinafter fully set forth.

Figure l is a perspective view, showing my I 5 evaporator in readiness for operation. Fig. 2 is a detail end view, showing the manner of attaching the steam-sections; and Fig. 3 is a vertical longitudinal section, showing the arrangement of the furnace, boiler, smoke-flue,

and steam-sections.

A is the brick foundation, upon which rests the evaporator. It is made hollow. and in its forward end is situated the furnace B, over which is the boiler O.

Extending from the furnace to the rear end of the foundation is a flue,which connects with the smoke-pipeD and supplies draft for the fire.

Extending horizontally from th upper rear end of the boileris a wide, flat steam e\ aporating-pipe, E. It rests upon the top of the brick foundation, and the steam in it is superheated by the contact of the pipe with the heated air passing along the flue beneath it, thus utiliz- 5 ing to the fullest extent the heat of the furnace. At the rear end of the evaporator this steam-pipe is provided with avertical section, E, which has formed around its upper edge the horizontal flange e, as shown in Fig. 2.

The second section of pipe extends the entire length of the lower section, and is provided with vertical sections E and flanges e, as set forth. The rear ends of alternate sections of the pipes E are provided with downwardly- 5 projecting sections E and flanges e, and the ends of the intermediate sections with upwardly-projectin g sections E, as shown in Fig. 2, to connect with the sections E above and below. The forward ends of the pipes E in the same manner are provided with upwardly and downwardly projecting vertical sections (No model.)

E, to afford means of communication to the adjoining sections. The flange e of the several sections may be bolted together or a clamp, I, placed around each end of theevaporator to hold them firmly together. This device is shown in Fig. 2.

The partitions F are placed in the spaces between the steam-pipe, and operate to brace the said pipes and to form convenient evapo- 6o rating-chambers for the fruit. The rear end of the upper steam-pipe E connects with the escape-pipe G,whioh has an outletin the smokepipe D. The partitions F are placed between the alternate sections of the pipes E where connections between the vertical sections E do not occur, as shown.

H is a series of drip-pipes, connecting with the forward ends of the steam-pipes and with a vertical pipe, the lower end of which enters the boiler below the level of the water in it. The steam which condenses in the steam-pipes escapes into this vertical pipe, and thence into the boiler.

The trough c in the forward end of the boiler is for the purpose of pouring water into the boiler and below the level of the water.

The steam-sections E may be of any desired length, and any required number of them may be placed together and joined, as shown.

The advantages secured by this construction and arrangement of the steam-pipes and of the partitions between are such that each pan of fruit will be separated from the other, the heat will be supplied to it both from above and below, and the pipes can be extended and increased in number without altering the arrangement of the pipes.
